"Last month, the EEOC filed a lawsuit against Estee Lauder in a Pennsylvania federal court alleging that Estee Lauder's parental leave policy discriminates against employees on the basis of gender by providing unequal benefits to biological mothers and fathers. What's notable about this lawsuit is that it involves a policy which, on its face, uses a 'primary' and 'secondary' caregiver distinction that provides different amounts of leave to employees based on that distinction without regard to their gender -- a practice used by many employers in their parental leave policies."
